B2C Custom Caches
Custom caches improve code performance by storing data that is expensive to calculate, takes a long time to retrieve, or is accessed frequently. Caches are defined in JSON files within cartridges and accessed via the Script API.
When to Use Custom Caches
| Use Case | Example |
|---|---|
| Expensive calculations | Check if any variation product is on sale for base product display |
| External system responses | Cache in-store availability or prices from external APIs |
| Configuration settings | Store configuration data from JSON files or external sources |
| Frequently accessed data | Product attributes, category data, site preferences |
Limitations
| Constraint | Value |
|---|---|
| Total memory per app server | ~20 MB for all custom caches |
| Max caches per code version | 100 |

b2c-docs
Search and read B2C Commerce Script API documentation and XSD schemas using the b2c CLI. Use this skill whenever the user needs to look up class methods, understand API signatures, find available properties on commerce objects (baskets, orders, products, customers), or check XML schema formats for imports. Also use when writing server-side scripts and needing API reference — even if they just say "what methods does Basket have" or "what fields can I import for products".
116b2c-webdav
List, upload, download, and manage files on B2C Commerce instances via WebDAV. Use this skill whenever the user needs to upload files to IMPEX directories, download exports from an instance, list remote files, create or delete directories, or zip/unzip files on the server. Also use when managing file transfers to sandboxes or browsing instance file systems -- even if they just say 'upload a file to the instance' or 'check what's in the IMPEX folder'.
103b2c-slas-auth-patterns
Implement SLAS authentication patterns in B2C Commerce including passwordless login (email OTP, SMS OTP, passkeys), session bridging between PWA Kit/Storefront Next and SFRA, hybrid authentication (B2C 25.3+), token refresh flows, trusted system on behalf of (TSOB), and JWT validation. Use this skill whenever the user asks about shopper authentication beyond basic login, token exchange flows, passwordless or biometric auth, keeping sessions alive across storefronts, handling 409 Conflict errors on token endpoints, refreshing shopper tokens, or validating JWTs — even if they don't mention SLAS by name.
90b2c-config
Inspect and debug CLI configuration, instance connections, and authentication. Use this skill whenever the user needs to check which dw.json or credentials are active, manage multiple instance profiles, retrieve OAuth tokens for scripting, troubleshoot authentication failures or connection errors, or integrate with VS Code or other editors. Also use when environment variables override config or the wrong sandbox is being targeted -- even if they just say 'why is it connecting to the wrong instance' or 'get me an access token'.
90b2c-controllers
Create storefront controllers using SFRA or classic patterns with server.get/post, middleware chains, and res.render/json. Use this skill whenever the user needs to build a page route, handle form submissions, create AJAX endpoints, extend or override existing controllers, or add middleware to a request pipeline. Also use when debugging route registration or response rendering -- even if they just say 'new page endpoint' or 'handle a POST request'.
86b2c-scapi-schemas
Browse and retrieve SCAPI OpenAPI schema specifications. Use this skill whenever the user needs to list available SCAPI APIs, inspect endpoint paths or request/response shapes, explore data models for products or orders, check which fields an API returns, or understand SCAPI versioning. Also use when looking up API details before building an integration -- even if they just say 'what fields does the product API return' or 'show me the SCAPI endpoints'.
